對於可能是一個明顯的問題，我提前表示歉意，但我一直試圖讓這一整天工作，我無法弄清楚如何讓這個工作。簡而言之：我的RMIregistry找不到我的RMI服務器應用程序的接口類。Java RMI服務器問題
我通過Eclipse中運行rmiregistry.exe這些論點：
1234 -J-Djava.rmi.server.useCodebaseOnly=false
而且我得到了下面的RMI服務器：
package es.test.innova.pruebas.test;
import java.io.File;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
public class TestImpl extends UnicastRemoteObject implements Test
{
public TestImpl() throws RemoteException {}
public static void main(String args[])
{
try
{
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager());
}
TestImpl obj = new TestImpl();
Naming.rebind("rmi://localhost:1234/Test",obj);
System.out.println("Connected to registry!");
}
catch (Exception e)
{
System.out.println("HelloImpl err: " + e.getMessage());
e.printStackTrace();
}
}
@Override
public String validate(File f) throws RemoteException {
return "hello world";
}
}
然後我用這些參數運行：
-Djava.security.policy=C:\D\RMI\policy.all -Djava.rmi.server.codebase=file:/C:/D/Proyectos/Firma/validarfirma/
引用的策略文件是這樣的：
grant {
permission java.security.AllPermission "", "";
};
代碼庫參數引用項目的文件夾，通過我也嘗試將它指向文件夾的bin文件夾，甚至直接在.class文件中，正如本網站的其他答案中所述。
不管我怎麼努力，我不斷收到此錯誤：

類沒有找到。我試過手動運行所有的東西，而不是使用Eclipse，直接從.class文件夾運行rmi，將服務器編譯爲一個.jar文件，然後用它來代替......當然，我已經弄了很多代碼庫參數。我嘗試了所有我能想到的，但我卡住了。
事情是我必須設置錯誤的代碼或類似的東西，但我不知道如何。註冊表無法找到我的課程。
如果有人能幫助我，我會非常感激。謝謝閱讀。
你有沒有在同一個包TestImpl名爲Test的接口？ –
